Plate size limit in joint

[Navid.Nik]

Hi all,

I am checking a calculation for a connection. The column is HSS profile and the beam is a cold-formed C-section, and they are connected via a plate with bolts. In the report, it is stated that the value "S" should be at least 2.5*t2. It makes sense to have a limit here because of the effective width of the plate, but I cannot find a reference in which factor 2.5 is stated as the limit. Do you know a reference/ standard code about this?

I'd base it on the spacing of the fasteners for the CFS member with a minimum overhang sufficient for welding... [Correction} If you have a lot of these, plate t1 can be longer than plate t2.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?
